  • Patent number: 7958430
    Abstract: An improved flash memory device and method for improving the performance and reliability of a flash memory device is provided. According to one embodiment, a method for writing data to a memory device may include writing the data to a temporary storage location within the memory device before the data is copied to another location within the memory device, incrementing a count value to indicate that the data has been copied, and repeating the step of writing, if the count value is less than a threshold value. If the count value is greater than or equal to the threshold value, the method may write the data to an external memory controller, where the data is checked for errors and corrected if an error is found, before the data is copied to the other location within the memory device.

  • Patent number: 7939372
    Abstract: A semiconductor device package, a method of fabricating a semiconductor device package and a method of testing an integrated circuit utilizing a semiconductor device package are disclosed. Embodiments create a flip-flop semiconductor device package by coupling a semiconductor device, with a wire-bonded arrangement of conductive pads, in a face-up orientation beneath etched portions of multiple leadfingers. The flip-flop package offers improved signaling properties, durability, reliability, and package density at reduced cost given that the conductive pads of the device couple directly to the leadfingers, without requiring the manufacture of a new device or the rerouting of signal paths. The height of the package is also reduced by utilizing space beneath the etched portions of the leadfingers that was unused in conventional solutions. Additionally, the flip-flop configuration provides convenient means for exposing surfaces of the device and/or surfaces of the leadfingers.

  • Patent number: 7939371
    Abstract: A semiconductor device package, a method of fabricating a semiconductor device package and a method of testing an integrated circuit utilizing a semiconductor device package are disclosed. Embodiments create a flip-flop semiconductor device package by coupling multiple leadfingers to conductive pads of a semiconductor device using an interposer with electrically conductive traces. The semiconductor device may be positioned in a face-up orientation between the leadfingers such that a single surface of the interposer may couple to both the semiconductor device and the leadfingers. The flip-flop package offers improved signaling properties, durability, reliability, and package density at reduced cost given that the interposer is configurable, the traces offer more reliable and durable interconnections, the interposer enables use of a smaller semiconductor device with a higher density conductive pad arrangement to decrease package density, and the interposer is relatively inexpensive.

  • Patent number: 7929363
    Abstract: A method of optimizing memory cell write/read is disclosed. The memory cell write/read is optimized by first reading the memory cell data using the normal mode. Next the page latch data that was used to NV (Non-Volatile) write the memory is also read back directly from the page latches. The two data are then compared to verify a successful and optimized memory cell write/read. NV writes and reads are performed with various high voltage parameters and sense amplifier reference settings to arrive at the most optimal one that gives the largest sense window for best write/read reliability. The page latch read mode is also used as a DFT (Design for Test) test mode to check for page latch functionality and page address uniqueness without having to write the memory cell. The page latch is written with logic data and read out directly using the page latch read mode to verify page functionality.
